This plant, or one that resembles it, is dangerous. Identifying is not authorising: no app has the authority to tell you that you may eat or touch a plant.
The bluish spurge of fields and coastal sands, with a star-shaped cap of leaves and the same white sap as all its cousins. It is among the commonest in the Peninsula and one of the easiest to cut by accident.

How to tell it
An upright plant twenty to sixty centimetres tall, bluish or glaucous. Narrow linear leaves along the stem, and at the top a whorl of broader leaves beneath the inflorescence. The glands carry two sharp horns. Abundant white latex from any cut.
What it is confused with
No dangerous lookalikes known in the Iberian Peninsula.
What it is for
None. The latex burns skin and is especially dangerous in the eyes, where it causes serious corneal injury. The whole family's rule, no exceptions: white sap, hands away from the face.
